The model management component consists of both the Decision Support System models and the Decision Support System model management system. A model is a representation of some event, fact, or situation. As it is not always practical, or wise, to experiment with reality, people build models and use them for experimentation. Models can take various forms.Businesses use models to represent variables and their relationships. For example, you would use a statistical model called analysis of variance to determine whether newspaper, TV, and billboard advertizing are equally effective in increasing sales.Decision Support Systems help in various decision-making situations by utilizing models that allow you to analyze information in many different ways. The models you use in a Decision Support System depend on the decision you are making and, consequently, the kind of analysis you require. For example, you would use what-if analysis to see what effect the change of one or more variables will have on other variables, or optimization to find the most profitable solution given operating restrictions and limited resources. Spreadsheet software such as excel can be used as a Decision Support System for what-if analysis.The model management system stores and maintains the Decision Support System’s models. Its function of managing models is similar to that of a database management system. The model management component can not select the best model for you to use for a particular problem that requires your expertise but it can help you create and manipulate models quickly and easily.

Decision Support Systems• Decision support systems (DSS)– Offer potential to assist in solving both semi-structured and unstructured problems

• Handles large amounts of data from differentsources• Provides report and presentation• Offers both textual and graphical orientationCharacteristics of DSS
Components of DSS• There are three fundamental components ofDSS– Database management system (DBMS)– Model-base management system (MBMS)– User Interface Management Component
Database management system (DBMS)• The data management component performs thefunction of storing and maintaining the informationthat you want your Decision Support System to use.Organizational informationExternal informationPersonal information
Model-base management system (MBMS)• The model management component consists ofboth the Decision Support System models and theDecision Support System model managementsystem.• Businesses use models to represent variables andtheir relationships.• The model management system stores and maintainsthe Decision Support System’s models
Examples of MBMSWhat if ModelGoal Seeking ModelStatistical model
User Interface Management Component• The user interface management component allowsyou to communicate with the Decision SupportSystem.• It consists of the user interface management system.• The user interface is the part of the system you seethrough it when enter information, commands, andmodels.• This is the only component of the system with whichyou have direct contract.
